A substrate processing assembly includes an edge support 320 and a heat distributing plate 340 to absorb and transfer heat energy via radiation from a radiant heat source 380 to a substrate 302 on the edge support. The edge support defines a substrate support location to support a substrate at an edge of the substrate during processing. The assembly further includes a first heat distributing plate positioned generally parallel to the edge support. A plurality of edge support holding arms 350 is coupled to the edge support. The plurality of edge support holding arms is also coupled to the first heat distributing plate to hold the first heat distributing plate spaced part from the edge support. In another embodiment, the assembly can include a second heat distributing plate spaced apart from the edge support. In yet another embodiment, the substrate processing assembly can be used in a substrate processing apparatus that includes a chamber within which the assembly is located and a radiant heat source to provide radiant heat to the chamber. The structure of the processing assembly provides substrate processing assembly components that have a low thermal mass such that the temperature of the chamber can be quickly ramped up to operating temperature, thus significantly decreasing the time to process a substrate such as a semiconductor wafer. |
